Which layer of the atmosphere merges with space?

• exosphere

• troposphere

• stratosphere

• thermosphere

How would the density of the air affect someone climbing Mt. Everest?

• The dense air near the mountain's peak would affect a climber's balance.

• The air would be thinner near the peak of a high mountain, and the climber might need more oxygen.

• It depends on the gender and age of the climber.

• Trace amounts of inert gases are deadly at such high altitudes.

Which sentence best describes how clouds are formed?

• Air cools at different rates; this "lapse rate" determines a cloud's height and size.
